Answer 1

Answer:

1. Noise is unwanted sound considered unpleasant, loud or disruptive to hearing. From a physics standpoint, noise is indistinguishable from desired sound, as both are vibrations through a medium, such as air or water. The difference arises when the brain receives and perceives a sound
2. Noise pollution can negatively impact the body in significant ways, including elevated blood presure, impaired cognitive functioning, cardiovascular and psychophysiological effects, cause heart attacks, reduce performance, provoke annoyance responses and changes in social behaviour and other effects of chronic stre
3. The theory is based upon blockage of sound ray travel toward a particular receptor; however, diffraction of sound must be addreed. Sound waves bend (downward) when they paan edge, such as the ape of a noise barrier. Barriers that block line of sight of a highway or other source will therefore block more sound.

Answer:

Sound waves enter the outer ear and travel through a narrow passageway called the ear canal, which leads to the eardrum. The eardrum vibrates from the incoming sound waves and sends these vibrations to three tiny bones in the middle ear. These bones are called the malleus, incus, and stapes
